WIBE-COILING MACHINE.

To all whom it may concern:

Be it known that I, EMANUEL M'rrrr'rrz, a citizen of the United States, residing at Providence, in the county of Providence 6 and State of Rhode Island, have invented new and useful Improvements in Wire- Coiling Machines, of which the following is a specification.

This invention relates to certain new and useful improvements in wire coiling machines, and pertains more particularly to a machine for coiling wire upon a drum or reel. This application is a continuation of, and substitute in part for, an application 1 filed by me on March 15, 1922, Serial No.

The primary object of the invention is to providea machine of this t pe which has improved means for laying t e wire on the reel and for also effecting such laying by guiding of the laying means from the'previously laid convolution of the active layer.

A' further object of the invention is to provide a machine of the type mentioned 2 which has means for enabling regulation of the speed of guiding means according to the gage of the wire being reeled or coiled.

I nether object of the invention is to provide laying means which is capable of latorally and also vertically pivotal movements so as to compensate for any irregularities" such as kinks, which may appear in the wire. A still further object of the invention is to provide novel means for effecting clockwise and counter-clockwise movement of the actuating shaft or means of the Wirelayer.

The invention still further aims to provide, a machine which is efiicient in operation and which will effect the laying 0r coilin in an expeditious manner.

till further and other objects will be later-set forth and manifested in the course of the following description. i In the drawings:v Figure 1 is a side elevation of the invention; I

(In :proceeding in accordance with the present invention, a shaft 1 is employed mounted, upon uprights 2 and driven by a pulley and belt 3, the shaftl having a reel or drum 4 secured thereto so as to rotate therewith.

A sprocket wheel 5. is secured to the shaft 1 and has a chain 6jpassing therearound, the chain also passing around a sprocket wheel 7 carried by a shaft 8 the latter journaled in a frame 9. A disk 10 is carried by the shaft 8 and engages with and between a pair of opposed spaced disks 11 and 12,

mounted on a shaft 13 carried by the arms- 14 of a yoke having a hub15 rotatable on a shaft 16. The yoke is operated by an arm 17 which, as shown in Figure 2, may

= be formed'of an extension of the arm 14,

the arm 17 being pivotally connected at 17 to the lower end of a rod 18. The rod 18 is threaded at its upper end through a nut 19 and carries a hand wheel 20 by means of which the rod 18 can be turned and thereby raised or lowered to effect corresponding movement of the shaft 13 by pivotal movement of the yoke hub about the shaft 16. An indicator rod 21 is provided and which is pivoted to the arm 17, the rod having graduations on its upper end which are readable in conjunction with or in relation to a pointer 22 that is rigidly connected to the frame 9. The graduations indicate the, gage of the wire, the yoke being set in accordance with such as "will be later more fully set forth.

' The disk 11 is I the disk 12 is keyed thereon and is held by a spring 23 in resilient engagement wit u the disk 10.

The shaft 16 carries a sprocket 24 connected by a chain 25 to a sprocket 26, the latter mounted on a'clutch'member 27 freely rotatable on a shaft 28 journaled at the upper part of the frame 9. A clutch member 29 is also free'ly rotatable'on the shaft 28 fixed to the shaft13 while and has a gear 30 thereon, the latter in mesh with a gear 31 mounted on a stub shaft disposed between the clutch members 27 and 29. The clutch 36 is freely rotatable in an arm 37 which latter is carried by a rod 38 slidable in the frame9, and arm 37 being cushioned by a pair of coil springs 39 mounted on the rod 38 and engaging on opposite sides of the arm the sprlngs being engaged at their outer ends by" collars 40 rod 38. A pair of stops 41 and 42 are carried by the rod 38.

The wire laying device embodies a main frame or member, 43 provided with a threaded socket or nut 44 and an apertured arm 45 the latter'freely receiving the rod 38 in its aperture, while the nut 44 threadedly receives the threaded part 45 of the shaft 28. Wire guides 46 having anti-friction wire engaging rollers 47 thereon extend ver-.

tically from the frame 43 and are spaced to receive the wire there-between and to guide same to a pair of grooved rollers or wheels 48 carried by the frame 43. A T- shaped pivoting member 50 is pivoted at 51 to frame 43 so as to have vertical movement and pivotally carries the wire laying arm 52 at 53 so that the arm 52 has 'horizontal pivotal movement. The free outer end of the arm 52 has a fixed upper wire guide 53 slotted to receive the wire, and a pivoted concaved depending guide 54 which receives the convolutions and lies upon the previously laid convolution of the wire, as

depicted in. Figure 1. The arm of the T- member 50 is horizontally slidahle on the pin 51 and is tensioned by cushioning springs 53 encirciing the pin 51 and engaging oppcsite sides of said arm. Shaft 13 drives shaft 16 by chain 55, the latter engaging over sprocket 56 carried by shaft 16 over sprocket 57 carried by shaft 13.

In operation, the shaft 1 isdriven by the belt 3, the shaft in turn driving shaft 8 throu h the chain 6, and thereby disk 10. The isk 10 through friction drives the disks Hand 12 and thereby the shaft 13,

the latter through chain 55 driving shaft-Q 16. The shaft 16 through chain 34 drives gear 33 and the latter through gears 31 and 3!) drives clutch member 29.' The shaft 16 through .ehain 25 drives clutch member 27. As the clutch 36 contacts with either the member 27 or 29, the shaft 28 is caused to revolve either clockwise or counter-clockwise, thus effecting corresponding movement of the wire laying device, i. e., first in one direction along the longitudinal axis of the reel 4 and then in the opposite direction along such axis.

In the movement of the Wire laying device in opposite directions along the longitudinal axis of the reel 4 it will be apparent that the guide 54, by virtue of engagin the previously laid wire convolution C o the active layer on the reel, will cause the active layer to be laid according to the previ= ously laid convolution of the active layer. When the arm 45 engages stop 42, shaft 36 will be slid to the left of Figure 2, thereby compressing spring 39 against arm 37. and storing up power in the spring until the res-istance offered by the engagement of clutch member 29 with clutch 36 is overcome and the latter moved by the compress'edspring out of engagement with clutch member 29,

- at which time the power stored up in spring 39 is released and utilized to move clutch 36 into engagement with clutch member 27. Similarly, when arm 45 engages stop 41, the clutch 36 is engaged with the clutch member 29 by corresponding compression of the spring to the left of the arm 37 effecting movement of the arm 52 to the right of Figure 2. c

From the foregoing, it will be apparent that the arm 52 is caused to reciprocate along the length of the reel, being guided by the movement of the guide, 54 which responds according to the previously iaid convolution of the active layer.

By varying the position of the rod 18 determined by the gage wire being reeled, it will be seen that the yoke and thereby the disks 11 and 12 are caused to vary their relation to the disk 10, so that the speed of movement of the Wire laying device is thus increased or decreased according to the diameter of the" Wire being reeled or laid.

It will be noted that due to'the pivotal movement of the guide or shoe 54, and the cushioned movement of the arm 52, any kinks or irregularities in the wire, will not effect the functioning of the arm, since the latter can freely give or respond to such irregularities. The cushioning springs further function to compensate for any disalinement of the heads of the spool 4, so that should arm 52 when reaching its end of travel and contacting therewith will not prevent uniform laying of the wire.
